The study of population regulation and demography in natural habitats is critical for the conservation of rare and endangered species. We address the impact of cattle exclusion on the demographics of Magnolia dealbata (Magnoliaceae), an endangered species according to IUCN and Federal Mexican...

Magnolia dealbata Zucc. is an endangered species as a result of habitat destruction. A population in central Veracruz was studied to determine in which of two disturbed habitats (secondary succession forestand grassland) where M. dealbata grows the tree showed better survival. Its spatial...

Floral anatomy and ontogeny are described in six species of Magnoliaceae, representing the two subfamilies Liriodendroideae ( Liriodendron chinese and L. tulipifera) and Magnolioideae, including species with terminal flowers ( Magnolia championi, M. delavayi, M. grandiflora, M. paenetalauma) and...

Two new species of Magnoliaceae, Magnolia jaenensis and M. manguillo, from the Department of Cajamarca, Peru, are described. Magnolia jaenensis is similar to M. yarumalensis but differs in the shape of the leaves and sepals, number of petals, stem and carpels. Magnolia manguillo differs from M....

By using a modified biotin-streptavidin capture method, a total of 12 microsatellite loci were developed and characterized for Michelia coriacea (Magnoliaceae), a critically endangered endemic to Southeast Yunnan, China. The number of alleles (A) ranged from two to six in 30 samples of this...

Seeds were obtained from seven natural populations of Acacia dealbata, three natural populations of A. mangium and a seed orchard of A. mangium, representing the natural range of the two species. Polyploids were discovered in two of the seven populations of A. dealbata. The 2C DNA amount for...

Species diversity and genetic diversity, the most basic elements of biodiversity, have long been treated as separate topics, although populations evolve within a community context. Recent studies on community genetics and ecology have suggested that genetic diversity is not completely...

Nylanderia fulva (Mayr) (Formicidae) is an invasive pest ant that has been reported in Florida, Texas, Louisiana and Mississippi. Workers tend various honeydew producing hemipterans in Florida landscapes and natural areas. We sought to understand the seasonal foraging activities of N. fulva and...
